SPECIFICATION forming' part of Letters Patent No. 571,742, datedNovember 24, 1896.

Application tiled January 3l, 1896. Serial No. 577,522. (No mode-IJ To@ZK whom it 1x2/ay concern:

Be it known that I, AARON THOMAS Binn- ERD, a citizen of the UnitedStates, residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented cert-ain neuT and useful Improveinen ts inSash Clamps 5 and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the saine.

This invention has for its objects, among others, to provide a simpleand cheap sawclanip that can be folded so as to occupy but a minimumspace and which can be quickly and iirmly fastened in position upon abench or other support and which is practically selffastening and is animprovement on a siinilar device 'patented to nie July 1G, 1895, No.542,819, to which reference is made.

Uther obj ects and advantages of the invention will be obvious from aninspection of the description hereinafter more fully set forth.

In the dra-Wings, Figure l is a view in perspective, sh owing thesaw-clamp in position for use. Fig. 2 is an elevation showing thesaw-clamp folded or in the closed position.

Fig. 3 is a vert-ical section taken transversely on one .side of theoperating-levers.

Like letters of reference indicatie like parts throughout the severalviews.

Referring non' to the details ol the drawings by letter, A designatesthe body portion of the clamp, which is cast hollow throughout its majorportion to render it as light as possible and at the saine time affordthe requisite strength to withstand all ordinary uses to which it may besubjected. The upper end of the rear part B of the body port-ion A isprovided 4with a shoulder or stop G, and 'ini- Jnediately above the stopG the rear jaw D of the clamp is pivoted through its middle portion at Eto the upright or part B of the body portion. The rear jaw D is providedon its rear face With a shoulder or stop E', which engages the shoulderor stop C when the san'- elainp is in position for use. The ends of therear j aw D are bent backwardly at right angles to the main portion ofsaid rear jaw D and are provided with spurs A', which are de arm of thehollow standard.

signed to be driven into the bench or other support upon which thesaw-clainp is to be fastened when in use. The lower end of the rear partB of the body portion A is provided with a hole F for the passage of ascrewr for securing` the saw-ela1np in place when it is desired tolocate it permanently.

The front jaw G of the clamp is east with a groove extending,`throughout its length on its rear face, and this groove II is filled ateach end for a short distance With rubber, Wood, cork, or the like,which forin sounddeadeners I, which lessen the sound when an operator orWorkman is liling a saw held in the saw-clamp. The front jaw G ispivoted to the upper end of a slotted lever L, which is fulcrunied inthe upper end of the shorter The front jaw G is provided with a shoulderG', Which abuts against a shoulder G2 on the upper portion of theslotted lever L when the jaw Gf is in a horizontal position. Near thelower end of the standard is fulcruined a lever M, which is provided onone side, preferably near its inid- .dle, with a stud N, which projectsinto the slot P of the lever L and moves up and down therein when saidleve-r M is ope-rated to open and close the jaws of the saw-clamp. Theslotted lever L is provided near its upper end with a spring' Q, whichnormally bears upon the seniieireular front face of the front jaw of thesaW-cla1np and holds it in the horizontal position, that is, theposition it occupies when in use, but at the saine time permits it to beturned into the folded position, preferable for storage ortransportation. The left end of the front bar or jaiv is heavier thanthe other end of said bar or jaw, the extra Weight causing said jaw tobe normally held parallel with the rear jaw when in position for use.The spring secured to the slotted leif'eisarin serves to hold the frontjaw steady and parallel with the rear jaw when the saw clamp is in theWorking position.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

A sauf-clamp, comprising the body portion A., the rear portion B thereofprovided with shoulder C, jaWD pivoted at E and provided IOO withshoulder E and securing-spurs, slotted lever L pivoted to the front armof the body portion and provided with shoulder G2, jaw G pvoted to saidlever and provided with shoulder G', lever M pivoted to the frame and inoperative engagement with lever L and spring Q attached to said lever Land normally bearing upon jaw G to hold said j mv in horizontalposition, substantially as shown and described.

In testimony whereof I hereunto affix my signature in presenee of twoWitnesses.
